Nation's Largest Dairy Renewable Natural Gas Producer Announces Expansion of California Facility

PIXLEY, Calif., Jan. 13, 2020 /PRNewswire/ --A Calgren Dairy FuelsA and Southern California Gas Co.A (SoCalGas)A today announced that four additional Central Valley dairies have started sending methane produced from cow manure to Calgren's biogas operation in Pixley, where it is processed into high-quality, renewable natural gas (RNG) and injected into SoCalGas' system. The Calgren facility now collects methanea?? a potent greenhouse gas that would otherwise escape to the atmosphere and contribute to climate changea??from more than 66,000 cows at 10 area dairy farms. A The additional dairies are projected to nearly double the amount of RNG produced at the facility, further reducing greenhouse gas emissions and displacing more traditional natural gas. Calgren partnered with Maas Energy WorksA to develop these four new dairy digesters as well as the previous six dairy digesters that have been operating since 2018."Over the last five years, renewable natural gas use in the transportation sector has grown by almost 600 percent," said Sharon Tomkins, SoCalGas vice president and chief environmental officer. "We're looking to build on that success by delivering more renewable energy options to our customers, including renewable natural gas produced at farms, hydrogen made from surplus solar energy, and advanced fuel cell systems that can provide energy in extreme weather events. Each of these technologies will be essential to promoting the long-term reliability of our energy systems and to meeting California's ambitious climate goals affordably." "Calgren is leading efforts in California on this front, working with both dairies and SoCalGas to mitigate emissions," said Lyle Schlyer, president of Calgren Renewable Fuels. "This facility alone will eventually capture methane produced from the manure of more than 75,000 cows, preventing about 130,000 tons of greenhouse gas emissions from entering the atmosphere each year, the equivalent of taking more than 25,000 passenger cars off the road annually." Renewable natural gas can rapidly cut greenhouse gas emissions (GHGs) because it takes more climate pollution out of the air than it emits as an energy source.A The RNG produced at Calgren's facility today is used as a carbon-negative fuel for heavy-duty vehicles like transit buses and long-haul trucks. RNG can also be delivered to customers to generate clean electricity and heat homes and businesses. Last year, SoCalGas committed to delivering 20 percent of the natural gas it buys for homes and businesses from renewable sources by 2030. More than 80 percent of all methane emissions in California come from organic sources like wastewater treatment plants, landfills, food and green waste and farms. In California, a 2016 lawA requires a 40 percent reduction of methane emissions fromA waste sources such as landfills and dairies, with provisions to deliver that energy to customers.
